CS5332
CS5332 is Two-Phase Buck Controller manufactured by onsemi.
Two- Phase Buck Controller with Integrated Gate Drivers for VRM 9.0
The CS5332 is a two- phase step down controller which incorporates all control functions required to power high performance processors and high current power supplies. Proprietary multi- phase architecture guarantees balanced load current distribution and reduces overall solution cost in high current applications. Enhanced V2™ control architecture provides the fastest possible transient response, excellent overall regulation, and ease of use.
The CS5332 multi- phase architecture reduces output voltage and input current ripple, allowing for a significant reduction in inductor values and a corresponding increase in inductor current slew rate. This approach allows a considerable reduction in input and output capacitor requirements, as well as reducing overall solution size and cost.
